You cannot unlock (or "reset") a locked unit without the PIN number or going to the location where the PIN was set. The only other option you have is to send the unit to Garmin.

SOURCE: garmin 178c turns off on it's own.

Hi

Sounds very much like the wiring plug connections in the back, always overlooked but so important that connections are tight and contacting.

SOURCE: I have a Garmin 178c map/sounder and it will not

I have the same problem. Did you ever figure out why it was not loading? There are no software adjustments to be made. Just plug in the card and wait. It says its reading the card, but never goes any further. Let it 'read the card' for hours with no luck. Help!!!

My Garmin GPSMAP 178C screen backlight failed


Backlight problem: Remove the display, remove the light tube from behind the LCD. Buy a led panel from Ebay for around $5 and install it behind the LCD under the drfusing layers. Run the wires out to a 12 VDC source and there you have it.

GPSMAP 178C Sounder GPS Receiver: My 178C will not stay powered up. I just replaced ...


I had the same problem with mine. It is caused by a crimped wire on the internal harness inside the machine. I opened it up and discovered that when originally put together 3 of the wires from the plug were crimped. One was broken off. The only way to fix it is to open it up, restrip the wires place a piece shrink wrap on before you solder it back and then make the shrink wrap flush with the back of the plug and heat her up. And, Voila... no more intermittent operation. Hope this helps? John

Garmin 178c won't find satellites


It would appear that your Garmin has no clue as to where it is on the planet. I think a trip to the owner's manual:

http://www8.garmin.com/manuals/GPSMAP178CSounder_OwnersManual.pdf

might be your best bet to help initialize your unit. The info on how to graphically initialize your Garmin can be found on page 5.

Hope this is helpful.
Good Luck!
